Here’s the blurb from the Sabbath Manifesto site, which appears to be promoting the idea. A very Tempo-ish idea of figuring out how to slow down.

Way back when, God said, “On the seventh day thou shalt rest.” The meaning behind it was simple: Take a break. Call a timeout. Find some balance. Recharge.

Somewhere along the line, however, this mantra for living faded from modern consciousness. The idea of unplugging every seventh day now feels tragically close to impossible. Who has time to take time off? We need eight days a week to get tasks accomplished, not six.

The Sabbath Manifesto was developed in the same spirit as the Slow Movement, slow food, slow living, by a small group of artists, writers, filmmakers and media professionals who, while not particularly religious, felt a collective need to fight back against our increasingly fast-paced way of living. The idea is to take time off, deadlines and paperwork be damned.

In the Manifesto, we’ve adapted our ancestors’ rituals by carving out one day per week to unwind, unplug, relax, reflect, get outdoors, and get with loved ones. The ten principles are to be observed one day per week, from sunset to sunset. We invite you to practice, challenge and/or help shape what we’re creating.
